For industrial buyers, choosing the right stevia extraction machine decides your stevioside yield, purity, and final profit. Traditional hot-water methods are slow, energy-intensive, and leave 30-40% of glycosides in waste leaves. Our advanced ultrasonic stevia extraction machine from Xi’an Bioland Instrument Co.,Ltd. uses cavitation to break stevia leaf cells at 40-60°C, boosting extraction efficiency by 50-500% and cutting time by over 2/3, while preserving natural sweetness without bitterness.
Xi’an Bioland Instrument Co.,Ltd. is a professional manufacturer and solution provider for R&D production and sales of distillation, concentration, reaction, extraction, separation, filtration, purification, crystallization, emulsification, mixing, drying, and ancillary equipment for supporting those chemical process like heating, cooling and vacuum devices. It's been more than 15 years in such field. Our main products include ultrasonic plant extraction machine, Ethanol extraction machine, extraction concentration unit, and more.
Industrial stevia production demands more than just an extractor; it needs a stable, GMP-compliant system that guarantees consistent Reb-A content batch after batch. The core advantage of our stevia extraction machine lies in its integrated design of ultrasonic breaking, low-temperature extraction, and vacuum concentration in one closed loop. Based on our product line at https://www.biolandequip.com/ultrasonic-extraction/stevia-extraction-machine, this configuration ensures higher purity, lower solvent loss, and continuous operation for large-scale manufacturing.
Client pain point is low yield. Many factories using conventional reflux only get 8-10% stevioside from dried leaves, with large residue waste. The industry challenge is that stevia cell walls resist solvent penetration. Our stevia extraction machine solves this with ultrasonic physical effects that cause plant tissue to break or deform, making active ingredients fully released. One client in Southeast Asia increased yield from 9.2% to 16.5% in 35 minutes.
That yield jump directly improves ROI. Because our stevia extraction machine extracts more thoroughly, the same raw material produces more finished product. With motor power 2.7-3.5 KW and evaporation capacity 20-200 kg/h, you can process more batches per day without adding labor, turning waste leaves into profit.
High temperature creates bitter aftertaste and dark color in stevia extract. Traditional boiling at 100°C degrades heat-unstable glycosides and dissolves excessive pigments and pectins. Our stevia extraction machine operates at best temperature 40-60°C under vacuum -0.05 to -0.09 MPA, protecting sweetness profile and reducing impurities for easier purification.
This low-temperature advantage is proven in our tea extraction machine and Coffee Extraction Machine projects. For green tea, we extract tea polyphenols, aromatic oils, and amino acids at low heat to keep antioxidant activity. The same principle helps our stevia extraction machine produce light-colored, high-purity stevioside that meets food and beverage standards without heavy decolorization.
Manual operation leads to batch variation and quality complaints from beverage customers. Our stevia extraction machine features intelligent PLC electrical control system, online concentration monitoring, automatic discharging, and CIP online cleaning. You set solvent ratio, temperature, and time once, and the system executes automatically for repeatable results.
Continuous feeding and discharging make concentration pipelined, continuous, and automated. The stevia extraction machine monitors evaporation temperature 60-100°C, jacket pressure 0.09-0.3 MPa, and system vacuum -0.085 MPa in real time. Operators receive alarms if parameters drift, preventing failed batches and ensuring stable production for export orders.
Export to Europe and USA requires strict GMP/FDA compliance. Our stevia extraction machine is universally manufactured with SUS304/316L stainless steel, equipped with three-layer insulation, defoamer on top of extraction tank and evaporator, and full CIP online cleaning design. It can work under negative, normal, and positive pressure for water or ethanol extraction.
Our products are also exported to Europe and Southeast Asia and other regions. We have ISO safety guarantee and CE certification give you excellent quality promise. This certification advantage helped a European natural sweetener brand pass their audit using our stevia extraction machine, avoiding costly re-equipment and accelerating market entry.
When scaling from lab to factory, many extraction systems fail to maintain linear performance. Ultrasonic power density drops, heating becomes uneven, and yield collapses. Our stevia extraction machine family is designed for true scale-up, offering five standard models with identical control logic so your pilot recipe directly transfers to industrial output without re-optimization.
We offer BL-TN-C50L, C100L, C200L, C300L, and C500L for our stevia extraction machine, covering volumes 50 to 500L. A university or startup can begin with 50L for R&D and small pilot production, validate parameters for extracting stevioside from leaves, stems, and roots, then scale to 500L industrial line with same PLC program.

This scalable design protects your investment. One client in Mexico started with 100L stevia extraction machine for local beverage supply, then added a 300L unit within eight months as demand grew. Because both machines share structure and operation, training time was zero and production doubled quickly with consistent quality.
Throughput bottleneck is often concentration, not extraction. Our stevia extraction machine integrates extraction and concentration. The evaporation capacity ranges from 20 kg/h for 50L model to 200 kg/h for 500L model, with steam consumption 25-250 kg/h. This matching ensures extract is concentrated into required specific gravity ointment without waiting.
The closed-loop design recycles solvent. Secondary steam from concentration goes through condenser and cooler, becoming condensate that refluxes to extraction tank as fresh solvent. New solvent flows from top to bottom through material layer, dissolving soluble components until extraction liquid becomes colorless. Our stevia extraction machine achieves near 95% solvent recovery.
Traditional stevia extraction needs 3-5 hours per batch with multiple boiling cycles. Our stevia extraction machine completes best extraction in 24-40 minutes due to cavitation-enhanced mass transfer. This time cut by over 2/3 means you can run 6 batches per day instead of 2, tripling capacity without extra floor space.
Case: A Paraguayan processor struggled with long cycles and high energy bills. Pain point was limited daily output and dark extract. Solution: Replace old reflux with 200L stevia extraction machine with thermal oil heating option for sites without steam. Actual benefit: Cycle dropped to 38 minutes, electricity down 32%, and extract color improved from brown to light yellow.
Energy and ethanol costs determine margin in stevia business. Our stevia extraction machine uses low-temperature ultrasonic extraction, so jacket pressure and evaporation temperature are lower than traditional methods. Vacuum pump maintains -0.085 MPa system vacuum, allowing concentration at 60-100°C, saving steam and preventing thermal degradation.
The main products include ultrasonic plant extraction machine, Ethanol extraction machine, extraction concentration unit, co2 extraction machine, supercritical fluid extraction equipment, essential oil distillation equipment, and more. This portfolio expertise allows our stevia extraction machine to adapt to water extraction for crude glycosides or ethanol extraction for high-purity Reb-A, with solvent fully recovered for next batch.
Selecting a stevia extraction machine for large-scale use is not just about volume; it is about matching your raw material, solvent strategy, automation needs, and compliance targets. As a process solution expert, we evaluate your whole workflow to ensure the machine solves real production problems, not just performs lab extraction.
Stevia leaves contain highest glycosides, but stems and roots also have recoverable value. Different parts have different fiber density and require different ultrasonic power. Our stevia extraction machine has broad adaptability, not limited by component polarity or molecular weight, suitable for leaves, stems, and roots, and even other botanicals.
This flexibility was proven in ultrasonic extraction mushrooms projects. We extract polysaccharides from Ganoderma lucidum, shiitake mushrooms, and sweet potato with same core ultrasonic system by adjusting parameters. Clients using our stevia extraction machine can therefore switch to mushroom polysaccharide line or goji polysaccharide line in off-season, improving asset utilization.
Water extraction gives high yield but more impurities; ethanol gives higher purity Reb-A. Our stevia extraction machine supports both, plus multi-function modes: ultrasonic low-temperature extraction, solvent extraction, ultrasonic normal temperature extraction, Soxhlet dynamic extraction, hot reflux extraction, water precipitation, alcohol precipitation, and percolation.
This multi-function extraction is valuable for diversified factories. The same stevia extraction machine platform is used as tincture extraction machine for ethanol extraction of medicinal herbs, as propolis extraction machine for flavonoids and phenolic acids via ultrasonic-assisted ethanol extraction, and as pigment extraction from plants for orange peel pigment and anthocyanins, betaine, carotenoids, and chlorophyll.
Labor shortage and human error cause inconsistent glycoside content. Our stevia extraction machine reduces labor through PLC automation, metering tank, storage tank, liquid pump, filter, and automatic discharge. One operator can monitor two lines via central control cabinet, cutting labor cost by 50% compared to manual reflux.
Application scenario: A Chinese health food company had 6 workers per shift for manual stevia extraction. Pain point: High turnover and batch failure rate 12%. Solution: Install 300L stevia extraction machine with online concentration monitoring and automatic cleaning. Actual benefit: Staff reduced to 2, failure rate dropped to 1.5%, and annual labor saving exceeded $45,000.
If you export to EU, US, or Japan, equipment must meet GMP, FDA, CE, and ISO standards. Our stevia extraction machine complies with pharmaceutical GMP and food HACCP requirements, with documentation support for validation. The stainless steel contact parts, three-layer insulation, and CIP system ensure no cross-contamination between batches.
We also apply this compliance to other lines like Chilli Oleoresin Extraction Plant for capsaicin and chili oleoresin, extraction of flavonoids from ginkgo leaves, bamboo leaves, chrysanthemum, and lotus leaves, and ultrasound assisted extraction of quercetin from larch, celery, mulberry leaves, and sophora japonica. This track record gives confidence that our stevia extraction machine will pass your audits.
Stable 24/7 operation requires robust mechanical design, clear working principle, and easy maintenance. Our stevia extraction machine is engineered for continuous industrial use, not just laboratory demonstration, with components selected for durability and safety in food and pharma environments.
The stevia extraction machine structure consists of ultrasonic system, extraction tank, tubular heater, evaporator, condenser, oil separator, oil receiver, liquid pump, metering tank, storage tank, filter, vacuum pump, and distribution cabinet. Extraction tank and evaporator top vapor outlets both have defoamer to prevent overflow and product loss.
For units without steam heating, we can add thermal oil heating system. All tanks use SUS304/316L with sanitary fittings. This industrial-grade construction ensures our stevia extraction machine runs stably for years, even with corrosive ethanol solvents, reducing downtime and maintenance costs for large-scale manufacturing.
The operating principle of our stevia extraction machine involves specific steps. First, the stevia raw material is loaded into the extraction tank, and a solvent—such as water or ethanol—is added at a ratio determined by the production process. Set extraction temperature per need, typically 50°C, and start ultrasonic extraction per SOP for 24-40 minutes.
After extraction, open pipeline valves in order, pump liquid into concentration tank for vacuum concentration. Set concentration temperature, keep vacuum -0.05 to -0.09 MPA. Secondary steam condenses and returns to extraction tank as new solvent, forming reflux extraction until complete dissolution. Concentration continues until required specific gravity ointment, while colorless liquid in extraction tank can be reused.
Safety is critical for ethanol extraction. Our stevia extraction machine includes explosion-proof options, pressure relief valves, and PLC interlocks that stop heating if vacuum fails. The CIP online cleaning system cleans tanks, pipelines, and condenser automatically after each batch, preventing buildup and microbial contamination.
Maintenance is simple. Filters are quick-release, seals are food-grade, and ultrasonic transducers are modular for easy replacement. We provide operation manual, video training, and lifetime maintenance. Clients can schedule Factory Acceptance Test at our facility once goods are ready, testing their own stevia leaves on our stevia extraction machine before shipment.
Smart investors choose equipment that earns money all year. Our stevia extraction machine is also ideal for plant protein, wheat germ oil, tremella polysaccharide, soybean protein, jujube and goji active substances, rose essential oil, peppermint essential oil, valerian fragrance, caffeine, tea juice, functional food actives like polyphenols and flavonoids, marine fish protein, peony seed oil, and paprika red pigment.
For example, one client uses same stevia extraction machine line for tea polyphenols in spring and stevia in autumn, doubling utilization. Another uses it for pigment extraction from plants in summer. This multi-purpose design, combined with GMP compliance, makes our stevia extraction machine a profit center, not a single-product cost.
